I 'LUBRICATED SIDE BEARING.

Application filed February 2'7, 1922. Serial No. 539,478.

To all whom 2'25 mag concern:

Be it known that I, EDWIN G. BUssn, a citizen of the United States, residingat the city of Chicago, county of Cook, and State of Illinois, have invented a certain new and useful Improvement in Lubricated Side Bearings, of which the following is a full, clear, and exact description, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, forming part of this application, in which,

Figure 1 is a vertical sectional view of my improved lubricated side bearing.

Fig. 2 shows a section and an end view of a modified form,

Figure 3 is a side elevational view partly in vertical section of another modified form.

Figure 4 is a bottom plan view of the form shown in Figure 3.

This invention relates to a new and useful improvement in lubricated side bearings, being designed particularly for use in connection with top side bearings, i. e., those which are secured to the underframing of the car body, although my improvements may be used in the lower side bearing, i. e., that one which is carried by the car truck or its bolster. However, when used in connection with an upper side bearing, the gravity feed materially assists-in the lubrication.

In the drawings, 1 indicates a base plate of a side bearing, in this instance constituting the top wall from'which depends side walls 2 and a bottom wall 3, the latter being pro; vided with a series of openings or perforations 3, as shown.

4 indicates a bore on the upper portion of the bearing, said bore having a port 4 at one end leading into a chamber 5, which latter is in communication with the ports 3 A plug 6 of the same or slightly larger di ameter than the bore 4 is threadedly mounted in an opening in one of the side walls in alignment with the bore 4i through which opening a reaming or finishing tool for the bore l may be inserted for well-understood purposes.

7 indicates a piston head mounted on the inner end of a rod 8 having threaded engagement with an opening in one of the side walls of the bearing, said rod 8 having a handle 9 upon itsouter end by which it may be turned and the piston?- forcedinwardly in itsbore.

In operation, waste is inserted into the chamber 5, after which the bore in chamber 5 is filled with grease or other lubricant.

The piston head 7 should be in its outermost position at the time. The plug 6 is now inserted and the grease 0r lubricant will feed by capillary attraction, assisted by gravity, through the ports 3 when the device is first loaded. 'TVhen the lower surface of the bearing becomes dry, or the lubricant is no longer self-feeding, as above indicated, :the rod 8 can be rotated, forcing the piston head 7 inwardly, this action constituting a forced feed, whereby the lubricant is compelled to pass through openings or ports 3* by pressure. The handle 9 can be turned from time to time as lubricant is required until its movement is arrested, after which the bearing will have to be recharged with lubricant.

In Figure 2, I have shown a. similar, construction except that the plug 6. has been omitted and a packing nut 10 is used at the end of the bore.

In Figures 3 and 4, I have shown another form in which I have provided an overflow and compression chamber 11 in the upper portion of the bearing. In this form, as in Figure 2, thepacking nut 10 and its carried piston and piston rod may be removed for the purpose of inserting waste in the chamber 5 and charging thefbearing with the lubricant. The chamber 5 communicates with the chamber 11 by meansof an opening 12. When first charged the chamber 11 may be filled with lubricant, and as this seeps through the waste to the ports 3, the piston may be forced inwardly so as to exert a pressure on the lubricant, and at the same time place any air which may be trapped in chamher 11 under pressure, which air pressure cating device as adapted to side bearings for railway cars, it is obvious that this same principle can be employed in connection with third. or fourth point supports for brake beams; and, also, that waste need not be employed, unless desired.

What I claim is:

l. A lubricated bearing comprising a housing having an apertured contact Wall.

on one side, said housing being provided with a horizontally disposed bore and a horizontally disposed lubricant chamber superposed in relation to, and in communication with each other, a piston in said bore, and means for operating said piston.

2. A lubricated bearing comprising a housing having an apertured contact wall, said housing being provided With a horizontally disposed lubricant chamber and a horizontally disposed cylindrical bore superposed. in relation to, and in communication wlth each other, a piston in said bore, and

removable means in the housing for giving access to the lubricant chamber through said piston bore.

3. A lubricated bearing comprising a housing, an apertured contact wall on one side'of said housing, said housing having a bore, a lubricant chamber and an overflow chamber all, in communication with each other, a piston in said bore, means for operating said piston, and removable means arranged in the housing for giving access to said piston and said lubricant chamber.

In testimony whereof I hereunto afiix my signature this 17th day of February, 1922.
